Does anyone know how employer information is reported to the credit agencies? Is this something your employer does, or is it based on the employer that you list on credit card applications?

I'm only asking because I started a job at New York University 6 months ago, and my previous employer is still on all of my reports. I thought that if the employer that I list on applications doesn't match the one on my reports, it may cause problems.

I know that I can contact the agencies with proof of employment to get things changed, but was just wondering how it gets updated.

Thanks
